Introducing the *structured* IF and WHEN statements ?
Locked
 
|
Hi Gentlewomans (if any) and Gentlemens, as well ... ;-)
I shall like to *introduce* the so called STRUCTURED *IF* *and* STRUCTURED *WHEN* statements in NetRexx, all other dialects of Rexx, at your disposure &/ decision, as follows: Currently, syntax is: IF condition [;] THEN [;] statement WHEN condition [;] THEN [;] statement As we all (me too, of course) shall need and want to keep any and all old Rexx Programs running, *I* am asking You as *STUPID Question (as always, for those, who do know me...) *I* am proposing a third kind of IF and WHEN, having NO keyword THEN, following the IF and WHEN at all! Thus, new, proposed syntax will be: IF condition statements END IF SELECT WHEN selection --- note, NO THEN statements WHEN selection statements ... [OTHERWISE] statements END Concurrently, *I am suggesting*, that any END statement may be followed not only by the control-label or the control variable, but by the originating *verb* as well. Thus, we shall have (again) a *very STRUCTURED approach*! which shall reveal and resolve some of the ASSYMETRICS of the Rexx Language (all dialects) PRO's and CON's shall be welcome, of course... My experimental implementation does now follow those rules, and seems to act on all variations quite properly. When needed, of wanted, I shall proceed to forward a more explicit *definition* of the *structured* IF (and ELSE), and WHEN statements ... Also, using a construct as END SELECT *or* END IF shall be very anvantegous for the common HUMAN recognition of what we all are trying to do: HUMAN minded programming.

Some *needed* new definitions in NRL3 shall be:
-- an explicit appearance of the SEMICOLON in the code is equivalent to a CARRIAGE RETURN -- two succeeding SEMICOLONS (without a NOP in between are *forbidden* -- a SEMICOLON with a succeeding (CR/LF *or* LF (dependent on OPSYS) *is* equivalent to a single CR/LF (or LF), depending on opsys, and is *internally, in all Rexx dialects, always denoted as an *EOS*, which is an ACRONYM for the End of Statement .... Thus, as proposed already years ago ... The currenlty *optional SEMICOLONS* in the IF Syntax shall becode a *semantic meaning*, ****PLEASE**** Massa Thomas ;-) ====================================================================================== Am 18.01.2013 04:31, schrieb Thomas Schneider: > As some of you might recognize: > > it's hard to kill my thoughts (of thumb) ... > > Still alive, and again able to work ... > Thomas. > > > Waiting for: OH NO, OH NO, do NOT change &/ invent anything *new* .... > <grin> > ====================================================================== > Am 18.01.2013 04:13, schrieb Thomas Schneider: >> Hi Gentlewomans (if any) and Gentlemens, as well ... ;-) >> >> I shall like to *introduce* the so called STRUCTURED *IF* *and* >> STRUCTURED *WHEN* statements in NetRexx, >> all other dialects of Rexx, at your disposure &/ decision, as follows: >> >> Currently, syntax is: >> >> IF condition [;] THEN [;] statement >> WHEN condition [;] THEN [;] statement >> >> As we all (me too, of course) shall need and want to keep any and all >> old Rexx Programs >> running, *I* am asking You as *STUPID Question (as always, for those, >> who do know me...) >> >> *I* am proposing a third kind of IF and WHEN, having NO keyword THEN, >> following the IF and WHEN at all! >> >> Thus, new, proposed syntax will be: >> >> IF condition >> statements >> END IF >> >> SELECT >> WHEN selection --- note, NO THEN >> statements >> WHEN selection >> statements >> ... >> [OTHERWISE] >> statements >> END >> >> >> Concurrently, *I am suggesting*, that any END statement may be followed >> not only by the control-label or the control variable, but by the >> originating *verb* >> as well. >> >> Thus, we shall have (again) a *very STRUCTURED approach*! >> >> which shall reveal and resolve some of the ASSYMETRICS of the Rexx >> Language (all dialects) >> >> PRO's and CON's shall be welcome, of course... >> >> My experimental implementation does now follow those rules, and seems >> to act on all variations quite properly. >> >> When needed, of wanted, I shall proceed to forward a more explicit >> *definition* >> of the *structured* IF (and ELSE), and WHEN statements ... >> >> Also, using a construct as END SELECT *or* END IF shall be very >> anvantegous for >> the common HUMAN recognition of what we all are trying to do: >> >> HUMAN minded programming. >> >> Thomas Schneider. >> > > -- Thomas Schneider, IT Consulting; http://www.thsitc.com; Vienna, Austria, Europe _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/

Only because you asked for it:
" OH NO, OH NO, do NOT change &/ invent anything *new* ...." it's hard to kill my thoughts (of thumb) ... "Don't kill them. Just try to not get or to forget them. You are wasting our but foremost YOUR time!!!!

Walter, and all, pls. keep in mind:
*Inventions* have been always made in History .... *And*: even a *good Invention*, as NetRexx, and/or Rexx, shall need some enhancements, I think, to be able to survive ... Full Stop, from my side ...
